  • The handle were observed by objective and subjective method as the washing was repeated for 4 kinds(sample A, B, C, D) of materials which have different water vapor transmission, and the change of water vapor transmission each others. The results of factor analyses for 18 polar adjective words on subjective handle test yielded 4 factors, that were 'elastic property', 'surface property', 'thickness and weight property' and 'thermal and rigid property'. The surface properties were deteriorated remarkably as washing was repeated and significant difference were observed. Compared with the primary hand value for each materials, the statistical difference of samples was shown at Koshi and Fukurami measured by the KES-FB system. Koshi decreased for all the materials after repeated washing, and Fukurami had a tendency to increase for all the materials in proportion to repeated washing. Significant difference of total hand value wasn't shown in repeated washing number, but in fabric types.

  • 수증기 투과성과 DMMP 방호성능을 가지는 cellulose acetate butyrate (CAB)/polyethyleneimine (PEI) 기반의 선택투과막에 대해 여러가지 첨가제를 적용하여 CEES에 대한 방호성능 개선을 시도하였다. 시험결과, CAB/PEI 기반의 선택투과막은 수증기 투과성은 그대로 유지하면서(${\geq}1,800g/m^2/day$), CEES에 대한 방호성능의 개선을 보여주었다($7.1{\sim}11.5{\mu}g/cm^2{\cdot}24hr$). 이 중, $Ag^+$ 이온과 이온교환수지 혼합물을 포함한 CAB/PEI 선택투과막에서 가장 우수한 방호성능을 확보하였다. 그리고 시험한 모든 선택투과막은 생물학작용제를 모사할 수 있는 다양한 크기의 에어로졸 입자($0.005{\sim}3{\mu}m$)에 대해서도 방호성능을 가짐을 확인하였다.

  • This study aimed to determine the effects of relative humidity and fiber properties on the moisture permeability of multilayer systems by measuring water vapor transmission in the overlapping condition of various fabrics. The results confirmed that the property of the fabric in contact with the humid environment affects the moisture permeability. If the layer facing the humid environment is hydrophobic and the layer facing the dry environment is superhydrophobic, water vapor transmission increases by up to 17.8% compared to the opposite conditions. Comparing the correction values of the water vapor transmission reflecting the thickness of the specimen under the multilayer condition showed that permeability was higher when the hydrophilic or hydrophobic layer was facing the humid environment. The opposite was true from the "push-pull" effect of absorption mechanism. In the case of moisture permeability, the more hydrophilic the surface facing the humid environment, the more permeable that water vapor diffuses and passes through. It was concluded that the "pull-push" effect, in which water vapor diffuses widely through the hydrophilic facing a humid environment and then passes through the hydrophobic layer, contributes to the improvement of permeability. Permeability differed according to the multilayer overlapping condition. When the relative humidity was high, the "pull-push" effect was insignificant. This is caused by water droplets absorption after the partial migration of water due to condensation. These results suggest that the overlapping conditions and properties of fabrics should vary depending on heavy sweating or not.

  • 본 연구에서는 심한 소음으로 불쾌감을 주는 스포츠웨어용 PTFE 라미네이팅 투습발수 직물 8종을 대상으로 직물 마찰음의 심리음향학적 특성을 고찰하고, 심리음향학적 특성에 영향을 미치는 직물의 기본 특성과 역학적 특성 간의 관계를 파악함으로써, 직물의 심리음향학적 마찰음을 낮출 수 있는 변인을 찾아내고자 하였다. 직물 마찰음 시뮬레이터를 이용하여 녹음한 직물의 소리에서 Zwicker의 파라미터인 심리음향학적 크기(loudness(Z)), 날카로움(sharpness(Z)), 거칠기(roughness(Z)), 그리고 변동강도(fluctuation strength(Z))를 계산한 뒤, 소리특성에 대한 사후검정 결과에 따라 시료를 덜 시끄러운 PTFE 필름 그룹과 더 시끄러운 PTFE 필름 그룹으로 나누어 마찰음의 심리음향학적 특성과 직물의 역학적 특성, 기본특성간의 관계를 고찰하였다. 심리음향학적 특성 중 loudness(Z)만이 시료의 마찰음과 유의한 관계에 있는 것으로 나타났으며, 분석 결과 직물의 기본 특성에서는 layer가 얇고 필라멘트사를 사용한 직물의 마찰음이 덜 시끄럽게 인지되는 것으로 나타났으며, 직물 마찰음의 심리음향학적 크기에 영향을 미치는 주요변수로는 layer로 것으로 나타났다. 마찰음이 작은 PTFE 필름 그룹의 경우 전단 방향으로의 변형이 어려울수록 마찰음이 시끄나타났다. 시끄러운 마찰음을 갖는 PTFE 필름 그룹의 경우 심리음향학적 크기에 영향을 미치는 주요 변수로 전단이력이 설명 변인으로 포함되었다.

  • 스포츠웨어는 착용 중의 쾌적함을 위하여 자연환경의 변화, 인체의 운동 및 활동 상황에 맞추어 그 기능을 적절히 조절할 수 있어야 한다. 인체는 체온 조절을 위해 땀을 흘리고 이 땀이 의복 밖으로 원활히 방출되지 못하면 덥고 습한 온열 생리적 불쾌감이 유발된다. 그러므로 온열적 불쾌감을 발생시키지 않도록 하는 것이 스포츠웨어가 가져야 할 중요한 기능이다. 이러한 환경 및 인체변화에 대응하여 투습ㆍ발수 소재가 일상 스포츠 웨어의 소재로 널리 쓰이고 있다. (중략)

  • Studying awareness, importance, satisfaction, and wearing behavior of functional textiles for active silver generation related with gender and age is expected to contribute to clothing products development to improve and maintain their health and marketing strategy fit for user characteristics. For empirical research, a survey was developed and the aged 50 and above were 332 respondents. The results of the study are as follows. First, silver generation considered all the clothing comfort sensations important when wearing clothes, such as tactile sensation, clothing pressure sensation, thermal/wet sensation, and motion sensation in human physiological aspect. Also, stretchy fabrics were ranked first in awareness, the number of wearing times, and satisfaction of comfort functional fabrics. More than 30% of silver generation have fifteen items out of 36 functional clothes. Second, in analysis of awareness by gender on functional clothing products, women were more aware of health/safety-oriented fabrics than men were. Otherwise, men had more knowledge about the water-related properties of functional fabrics than women have, such as water/moisture absorptive and water-repellent/vapor permeable fabrics. While women have more indoor casual wear, men had more active sportswear. Also, women expressed a strong preference to the stretchy function of fabrics.

  • The purpose of this study was to evaluate the mechanical thermal resistances and comfort properties of ski wear made with vapor-permeable water repellent (VPWR) fabrics and thermal insulation battings. Four types of experimental clothing were made with the combination of two VPWR fabrics (Hipora-$TM^{\circledR}$, Hipora-$CR^{\circledR}$) and two thermal insulation battings ($Viwarm^{\circledR},\;Airseal^{\circledR}$). Thermal resistances of ski wear were objectly evaluated by thermal manikin experiment ($21{\pm}\;2^{\circ}C,\;50{\pm}5\%$ R.H.,0.25 m/sec air velocity) and thermographic accessment ($2{\pm}2^{\circ}C,\;0\%$ R.H.,0.25 m/sec air velocity, and emissivity level : 1). Garment wear tests of ski wear included the measurement of the microclimate (inner temp. and relative humidity) of the experimental clothing by digital thermohygrometer and subject wear sensation using McNall's thermal comfort ratings. CBo values of experimental clothing 4 (Hipora-$CR^{\circledR}+Airseal^{\circledR}$) and 1 (Hipora-$TM^{\circledR}+Viwarm^{\circledR}$) were significantly higher than those of 2 (Hipora-$TM^{\circledR}+Airseal^{\circledR}$) and 3 (Hipora-$CR^{\circledR}+Viwarm^{\circledR}$). Thermal resistances in the points of breast, back, belly, and loin was significantly higher than those of upper am, fore arm, and shank of measuring points on the thermal manikin. According to the color map of the thermogram, the experimental clothing 4 indicated higher surface temperatures than the others showing more yellowish spots on the surface of clothing. Inner temperature of experimental clothing was not significantly different among the four types of ski wear, but relative humidities of experimental clothing were significantly different. Relative humidities of experimental clothing 1 and 3 showed higher than those of 2 and 4. Relative humidity of experimantal clothing was affected largely by the thermal resis- tance of thermal insulation batting materials. The subject wear sensation of experimental clothing 2 and 4 showed lower humidity than the others. Subject wear sensation was affected more by humidity sensation than by thermal sensation.
